fix(libs): pick up coa-ace3 3ec2009 (BlizOptionsGroup + Settings.* CoA-compat)

Re-sync after coa-ace3 3ec2009 added two CoA-compat patches:
  - AceGUI-3.0/widgets/AceGUIContainer-BlizOptionsGroup.lua: parent
    falls back to UIParent when InterfaceOptionsFramePanelContainer is nil
  - AceConfig-3.0/AceConfigDialog-3.0: Settings.* block guarded with
    fallback to InterfaceOptions_AddCategory on WotLK-era clients

Without these, every addon registering a Blizzard Interface Options
panel via AceConfigDialog errors on load on the CoA client.
